Form 8-K

File No. 033-13437

Dear Mr. Efron,

Del Taco Income Properties IV (the “Company”) is in receipt of the Staff’s letter dated December 5, 2006 regarding the Staff’s review of and comments on the Company’s Form 8-K filing referenced above. For your convenience, we have restated the Staff’s comments in bold in this letter and have provided the Company’s response below each comment.

Comment:

1. We note that Squar, Milner, Peterson, Miranda & Williamson, LLP succeeds Squar, Milner, Miranda & Williamson, LLP as your independent registered auditor. Please tell us if Squar, Milner, Peterson, Miranda & Williamson, LLP notified the PCAOB of the name change to their firm and when they anticipate having their registration with the PCAOB effective.

Response:

We were informed by Squar, Milner, Miranda & Williamson, LLP (“Squar Milner”) that, on December 6, 2006, the Public Company Accounting Oversight Board (the “PCAOB”) received a signed notification from Squar Milner and Squar, Milner, Peterson, Miranda & Williamson, LLP (“Squar Milner Peterson”) regarding the merger transaction and name change relating to Squar Milner. We have also been informed that such notification included all of the representations, consents, and other information required by the PCAOB in order to effect continuation of Squar Milner’s registration status.

We have been further informed by Squar Milner that, on December 8, 2006, the PCAOB notified Squar Milner Peterson that the aforementioned transaction and name change notification included all of the required information. Under these circumstances, continuity of Squar Milner’s PCAOB registration is automatic. Therefore, Squar Milner Peterson has concluded that effective December 8, 2006 it succeeded outright to Squar Milner’s registration with the PCAOB.

Comment:

2. We noted that the fourth paragraph of your item 4.01 disclosure does not specifically state whether or not Squar Milner’s report on your financial statements as of and for the year ending December 31, 2005 was qualified or modified as to uncertainty, audit scope or accounting principles. Please revise your Form 8-K to provide such disclosure which is specifically required by Item 304(a)(ii) of Regulation S-K. Please file an Exhibit 16 letter.

Response:

The Form 8-K referenced above has been amended to include such disclosure. In addition, a revised Exhibit 16 letter has been filed with the Form 8-K/A.

We have responded under a separate cover to the Staff’s comment requesting that the Company provide in writing certain acknowledgements.

Please do not hesitate to contact me with any questions or comments you may have.

Sincerely, DEL TACO INCOME PROPERTIES IV (a California limited partnership)
